Some high clouds came past around 18:00 but did not cause too much trouble. It blew out shortly after. More high clouds started rolling in around 01:00. Again, nothing terrible. Humidity crept up and down, but was trending higher as night went on. By 05:30 we exceeded safe limits and closed. We did not open again thereafter. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:51 dcamera 419( 503) 27 60 3.4 6.7 6.0 6.2 4.6 - 1.18 19:23 dcamera 314( 290) -76 60 2.7 4.4 4.2 4.2 3.3 - 1.07 21:46 dcamera 421( 340) -69 68 4.1 3.2 3.8 2.9 3.4 - 1.00 00:11 ecamera 368( -693) 58 72 2.6 2.0 2.9 2.1 2.7 ND3 1.01 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 27 9 228 (SW) 513 clear none 17:00 40 27 3 218 (SW) 590 clear none 18:00 38 27 3 274 (W) 543 mstly clr none 19:00 36 28 7 9 (N) 577 clear none 20:00 39 32 3 295 (WNW) 624 clear none 21:00 39 31 3 262 (W) 588 clear none 22:00 39 30 2 288 (WNW) 536 clear none 23:00 37 28 1 217 (SW) 557 clear none 00:00 37 28 4 263 (W) 437 clear none 01:00 36 31 6 154 (SSE) 689 mstly clr none 02:00 35 29 7 109 (ESE) 601 mstly clr none 03:00 39 27 3 197 (SSW) 550 mstly clr none 04:00 35 29 5 143 (SE) 691 mstly clr none 05:00 34 30 8 129 (SE) mstly clr humid 06:00 34 32 11 179 (S) mstly clr humid Note: the wind was coming from the azimuth listed.
